A 46 carat gem-quality pink diamond has been unearthed at Lucapa's Lulo mine in Angola. This is the largest gem quality colour diamond recovered from Lulo, which has become renowned for unearthing large gem quality diamonds such as 43 carat yellow diamond recovered in January and the 39 carat pink diamond recovered in September 2016.

Significantly, the 46 carat pink diamond, along with other large Specials, was recovered from new Mining Block 4, which is an area planned for resource delineation in 2018 to be included in the alluvial JORC resource update. This Mining Block is located close to the treatment plant.

The frequent recovery of large and premium-value diamonds from new areas along the Cacuilo River valley continues to illustrate the uniqueness and potential of the Lulo diamond concession. Lulo has already recovered 10 diamonds over 100 carats to date, including Angola's two biggest recorded white Type IIa gems weighing 404 carats and 227 carats.
